Description
Technical field
The utility model relates to a kind ofly can starch mixed uniformly blender with the liquid of two kinds of constructional materialss.
Background technology
The two fluid grouting method is to inject soil after a kind of material with two kinds of liquid pulpous state attitudes (such as water glass and cement paste) mixes according to a certain percentage also to solidify rapidly, with the intensity of raising soil and the constructure scheme of supporting capacity, it is widely used in the engineerings such as sealing leak stopping, ground stabilization.And in the process of two fluid grouting, can the material of two kinds of liquid pulpous state attitudes mix smoothly in blender and mix the direct quality that affects two fluid grouting.
Traditional double liquid grout injecting mixer is three-port structure, the deficiency of this blender is: under the conveying of two strands of liquid slurry in separately induction system, the process that mix the inside of spirt threeway, these the two strands liquid slurries that flow in opposite directions and mutually impact can produce turbulent flow, be difficult to the match ratio of two kinds of liquid slurries of accurately control, and mix inhomogeneously, make the mixed liquor slurry that injects soil after mixing to reach the effect of rapid solidification, finally affect the quality of whole construction works; In addition, two strands of liquid slurries in the tee piece are under the fluctuation of pressure, wherein one liquid slurry flows to the carrier pipe (be generally cement paste and flow to the water glass carrier pipe) of another strand liquid slurry easily under the effect of larger pressure, and mixes with another strand liquid slurry and to solidify, the carrier pipe that causes another strand liquid slurry is blocked and can't proceed the hybrid working that two kinds of liquid are starched.
For this reason, China Patent Publication No. be " CN 101892847 A " Patent Application Publication a kind of novel double liquid grout injecting mixer, it comprises vertically arranging for a kind of liquid starches injection, and the upper end is provided with the liquid slurry pipe of the hybrid chamber that communicates with it, and pass described liquid slurry pipe and stretch into another interior liquid slurry pipe of hybrid chamber, described another liquid slurry pipe upper end closed, the lower end is provided with the import of injecting for another kind of liquid slurry, the sidewall on another liquid slurry pipe top has through hole, the sidewall sheath of another liquid slurry pipe has the elastic caoutchouc cover that can cover through hole, in the process of implementing, starch pipe respectively injected water mud and water glass toward liquid slurry pipe and another liquid, when the pressure of water glass reaches predetermined value when above, the elastic caoutchouc cover can be strutted, and mix along being flow to hybrid chamber by the formed gap of lateral wall of the rubber sleeve after strutting and another kind of liquid slurry pipe, thereby produce turbulent flow when preventing the mixing of water glass and cement paste and affect mixed effect, and prevent in the carrier pipe of cement paste inflow water glass, cause the situation of water glass pipe frozen plug to occur.
But this novel double liquid grout injecting mixer still has weak point, its reason is, in the process of implementing, the pressure of water glass must be greater than the pressure (seeing the 14th section last two row of manual of this application) of cement paste, otherwise, water glass can't flow out from the through hole of another liquid slurry pipe, and along being sprayed into hybrid chamber by the formed gap of lateral wall of the rubber sleeve after strutting and another kind of liquid slurry pipe.And in the work progress of reality, different engineerings has different requirements to the mixing ratio of two strands of liquid slurries, and the pressure of mixing ratio and water glass and cement paste has direct relation, so, for satisfying various demands, just need to guarantee double liquid grout injecting mixer can the pressure of water glass greater than, when being equal to or less than the pressure of cement paste, water glass all can enter hybrid chamber and mix with cement paste, but obviously, the novel double liquid grout injecting mixer of this application only can just can carry out the mixing of two strands of liquid slurries during greater than the pressure of cement paste at the pressure of water glass, can't satisfy instructions for use.
Summary of the invention
The purpose of this utility model is to provide a kind of double liquid grout injecting mixer, and it can carry out the hybrid working of two kinds of liquid slurries in a larger pressure limit.
A kind of double liquid grout injecting mixer described in the utility model, the shell that comprises the tubulose with hybrid chamber, it is characterized in that: an end of described shell is provided with the first entrance that flows into hybrid chamber for a kind of liquid slurry, the other end of shell is equipped with the tube connector that flows to hybrid chamber for another kind of liquid slurry, the end that tube connector stretches into hybrid chamber leads to the core pipe, the core pipe is near the end sealing of the first entrance, the sidewall of core pipe has through hole, the inside of core pipe is provided with the core ball and can promotes the top spring that the core ball is blocked the outlet of tube connector, and the middle part of shell then is provided with the outlet for mixed slurries ejection.
The utility model leads to the core pipe that has it to seal near an end of the first entrance in the part that tube connector stretches into the hybrid chamber of shell, and offer through hole at the sidewall of core pipe, be provided with the core ball in the inside of core pipe and can promote the top spring that the core ball is blocked the outlet of tube connector, toward the pressure of the water glass of tube connector injected water glass or injection during less than the elastic force of top spring, the core ball since the effect of top spring with the path blockade of tube connector, can prevent that cement paste from flowing into tube connector and water glass carrier pipe, and two kinds of liquid need to be starched in the time of mixing, toward tube connector and the first entrance difference injected water glass and cement paste, when the pressure of water glass during greater than the elastic force of top spring, water glass will be blocked the core ball of tube connector outlet and push open, the path of tube connector is opened, at this moment, water glass flows into the core pipe from tube connector, and flow into hybrid chamber from the through hole of core pipe, mix with cement paste, and because from the approximate vertical that flows to of injection direction with the cement paste that injects from the first entrance of the water glass of through hole ejection, so water glass and cement paste can not produce turbulent flow when mixing, can guarantee mixed effect, obviously, the utility model, only need to can carry out at the pressure that guarantees water glass the hybrid working of water glass and cement paste greater than the elastic force of top spring, and do not need as prior art, need to guarantee that the pressure of water glass is greater than the pressure of cement paste, this shows, the scope of application of the present utility model is wider, can use in a larger pressure limit.
